Multi-operator calculator in C++?

[Iron_Cross]

Well yes, but you'd have to hadd a few other things first:

using System;
namespace Utils.Calc
{
    public class Calc
    {
        [paste code here]
    }
}

Then you would have to save that file as a .cs file. Then you would compile it with a C#.NET compiler. After all that then you could run the program.
